According to a union spokesperson, however, no official election by the 171 cleaning and maintenance professionals has taken place and, as a result, they are still legally represented by the union, the story stated.

A complaint against the ShastaRegionalMedicalCenter with the National Labor Relations Board alleging federal labor-law violations was filed by the SEIU on Thursday, the story noted.

Mary Schottmiller, attorney for the ShastaRegionalMedicalCenter, said: "[Administrators had received] objective evidence that a majority of the employees [no longer wished to be represented by SEIU … and] accordingly, the employer hereby withdraws recognition of SEIU."

Should the petition be ratified and accepted by the National Labor Relations Board, it would be the third time Shasta Regional employees had ousted a union, the story added.
